UltraPure™ Formamide (Invitrogen™)

UltraPure™ Formamide is commonly used for denaturing nucleic acids for sequencing gel electrophoresis, electron microscopy, and hybridization. A liquid at room temperature, UltraPure™ Formamide is vacuum distilled and packaged under dry nitrogen and can be used as supplied for many applications within three months of date of purchase. Because the breakdown products of formamide degrade nucleic acids, for sensitive applications formamide should be deionized by treatment with a mixed-bed ion-exchange resin immediately before use.
